Yosemite Valley is a glacial valley in Yosemite National Park in the western Sierra Nevada mountains of Central California, United States. The valley is about 7.5 mi (12.1 km) long and 3,000–3,500 ft (910–1,070 m) deep, surrounded by high granite summits such as Half Dome and El Capitan, and densely forested with pines. The valley is drained by the Merced River, and a multitude of streams and waterfalls flow into it, including Tenaya, Illilouette, Yosemite and Bridalveil Creeks. Yosemite Falls is the highest waterfall in North America and is a big attraction, especially in the spring, when the water flow is at its peak. The valley is renowned for its natural environment and is regarded as the centerpiece of Yosemite National Park.
Downieville is a census-designated place in and the county seat of Sierra County, California, United States. Downieville is on the North Fork of the Yuba River, at an elevation of 2,966 feet (904 m). The 2020 United States census reported Downieville's population was 290.
Kings Canyon National Park is an American national park in the southern Sierra Nevada, in Fresno and Tulare Counties, California. Originally established in 1890 as General Grant National Park, the park was greatly expanded and renamed on March 4, 1940. The park's namesake, Kings Canyon, is a rugged glacier-carved valley more than a mile (1,600 m) deep. Other natural features include multiple 14,000-foot (4,300 m) peaks, high mountain meadows, swift-flowing rivers, and some of the world's largest stands of giant sequoia trees. Kings Canyon is north of and contiguous with Sequoia National Park, and both parks are jointly administered by the National Park Service as the Sequoia and Kings Canyon National Parks.
The Gold Country is a historic region in the northern portion of the U.S. state of California, that is primarily on the western slope of the Sierra Nevada. It is famed for the mineral deposits and gold mines that attracted waves of immigrants, known as the 49ers, during the 1849 California Gold Rush.
The Folsom Lake State Recreation Area surrounds Folsom Lake in the foothills of the Sierra Nevada. The majority of it is owned by the U.S. Bureau of Reclamation and is managed by the California Department of Parks and Recreation. It is located near the city of Folsom, California, about 25 miles (40 km) east of Sacramento.
Malakoff Diggins State Historic Park is a state park unit preserving the largest hydraulic mining site in California, United States. The mine was one of several hydraulic mining sites at the center of the 1882 landmark case Woodruff v. North Bloomfield Mining and Gravel Company. The mine pit and several Gold Rush-era buildings are listed on the National Register of Historic Places as the Malakoff Diggins-North Bloomfield Historic District. The "canyon" is 7,000 feet (2,100 m) long, as much as 3,000 feet (910 m) wide, and nearly 600 feet (180 m) deep in places. Visitors can see huge cliffs carved by mighty streams of water, results of the mining technique of washing away entire mountains of gravel to wash out the gold. The park is a 26-mile (42 km) drive north-east of Nevada City, California, in the Gold Rush country. The 3,143-acre (1,272 ha) park was established in 1965.
State Route 49 is a north–south state highway in the U.S. state of California that passes through many historic mining communities of the 1849 California gold rush and it is known as the Golden Chain Highway. The highway's creation was lobbied by the Mother Lode Highway Association, a group of locals and historians seeking a single highway to connect many relevant locations along the Gold Rush to honor the 49ers. One of the bridges along SR 49 is named for the leader of the association, Archie Stevenot.
The Yuba River is a tributary of the Feather River in the Sierra Nevada and eastern Sacramento Valley, in the U.S. state of California. The main stem of the river is about 40 miles (64 km) long, and its headwaters are split into three major forks. The Yuba River proper is formed at the North Yuba and Middle Yuba rivers' confluence, with the South Yuba joining a short distance downstream. Measured to the head of the North Yuba River, the Yuba River is just over 100 miles (160 km) long.
Folsom Lake is a reservoir on the American River in the Sierra Nevada foothills of California, United States. Folsom Lake with its surrounding Folsom Lake State Recreation Area is one of the most visited parks in the California park system.
French Corral is an unincorporated community approximately five miles west of California State Highway 49 in Nevada County, California, United States.
The San Juan Ridge is a geographic feature extending approximately 24 miles (39 km) east-northeast between the South and Middle Yuba Rivers in the foothills of the northern Sierra Nevada. The elevation is approximately 790 m (2,600 ft) above sea level.
The North Bloomfield Mining and Gravel Company of North Bloomfield, California, was established in 1866 and operated a hydraulic gold-mining operation at the Malakoff Mine subsequent to the California Gold Rush. In its day, no other company's operations matched North Bloomfield Mining and Gravel Company in size or expense. The company operated until 1910. In the years prior, its profits and procedures had been reduced due to the landmark ruling of Woodruff v. North Bloomfield Gravel Mining Company.
Bridgeport is a former settlement on the Yuba River in Nevada County, California, 2 mi (3.2 km) from the town of French Corral. Its elevation is 567 ft (173 m) above sea level.
The American River is a 30-mile (50 km)-long river in California that runs from the Sierra Nevada mountain range to its confluence with the Sacramento River in downtown Sacramento. Via the Sacramento River, it is part of the San Francisco Bay watershed. This river is fed by the melting snowpack of the Sierra Nevada and its many headwaters and tributaries, including the North Fork American River, the Middle Fork American River, and the South Fork American River.
The 65.0-mile-long (104.6 km) South Yuba River is a left-entering tributary of the Yuba River originating in the northern Sierra Nevada at Lake Angela in Nevada County about three quarters of a mile north of Donner Pass, about three miles east of the town of Soda Springs. After passing through Lake Van Norden with Upper Castle Creek entering from the right, it gathers numerous snow-fed tributaries running west through a marshy, lake-filled valley, criss-crossing Interstate 80. The river briefly enters Placer County, then flows into Lake Spaulding, then plunges westward into a steep-sided valley. Canyon Creek enters from the right, then Poorman Creek also from the right near the town of Washington. The river continues west into the foothills, crossing under State Route 49. Its mouth is on the east shore of upper Englebright Lake, formed by a dam across the Yuba River.
John D. Olmsted was a California naturalist and conservationist most famous for creating the Independence Trail in Nevada City, California, as well as helping to save numerous other parcels across California, including Jug Handle State Natural Reserve in Casper, California, Goat Mountain in the Berryessa Snow Mountain Wilderness and the Bridgeport Covered Bridge. His efforts and vision of a park at Bridgeport led to the creation of the South Yuba River State Park, a 39-mile (63 km) length of Nationally protected Wild and Scenic land along the South Yuba River in Nevada County, California. Olmsted patterned his life after that of fellow environmentalist John Muir, with his trademark beard, formal clothing, and poetic and spiritual leanings towards the benefits of time spent in nature.
The Middle Fork American River is one of three forks that form the American River in Northern California. It drains a large watershed in the high Sierra Nevada west of Lake Tahoe and northeast of Sacramento in Placer and El Dorado Counties, between the watersheds of the North Fork American River and South Fork American River. The Middle Fork joins with the North Fork near Auburn and they continue downstream to Folsom Lake as the North Fork, even though the Middle Fork carries a larger volume of water.
The case of Woodruff v. North Bloomfield Gravel Mining Company was a lawsuit brought to California courts in 1882 where a group of local farmers sued North Bloomfield Mining and Gravel Company over damages caused to farmland in the Central Valley. The farmers who brought the suit claimed that the company's hydraulic mining operations resulted in the disposal of excess sediment, debris, and chemicals in local rivers. Prosecutors argued that the debris raised river beds and restricted flow in the rivers leading to heavy man-made flooding. In the years prior, flooding of debris and chemicals had destroyed a large portion of the valley's agriculture.
The protected areas of the Sierra Nevada, a major mountain range located in the U.S. states of California and Nevada, are numerous and highly diverse. Like the mountain range itself, these areas span hundreds of miles along the length of the range, and over 14,000 feet of elevation from the lowest foothills to the summit of Mount Whitney.
